Not exactly the solution you want but the Bruising Intellect trait makes an intimidate focused warder or harbinger (or vigilante) pretty functional.

Also remember when adept died there was talk of another VGA mystic to replace it.

Been thinking about it and.. What about a chaos themed archetype? Charisma and magic tend to have reckless connotations with the way sorcerer and wilders are fluffed and one of the MA's other features I liked was that it fully randomized your recovery.

Seems like you could expand on that and make something out of it
